Hazards of Volcanoes
Volcanic eruptions can erupt ash into the air, pour lava across the landscape, and contaminate water supplies. Landslides on volcanoes can occur even without an eruption. USGS assesses volcano hazards and develops hazard response coordination plans with emergency professionals.
